STANGHION.

Specification of Letters Patent.

Patented Jan. 20, 1914.

Application filed October 3, 1912. Serial No. 723,772.

To all whom it may concern:

Be it known that I, JOHN B. ()LnsoN, a citizen of the United States, residing at Fort Atkinson, in the county of Jefferson and State of Wisconsin, have invented a new and useful stanchion, of which the following is a. specification.

The present invention relates to improvements in stanchions.

The primary object of this invention is the provision of a novel form of means for swivelly supporting the stanchion both at its lower and upper ends, the upper end being in the form of a lock which will permit of the rotation of the stanchion without affecting the locking and releasing mechanism thereof.

A further object of the present invention is a construction of stanchion and lock therefor which simplifies the method of captivating the animal, and of releasing the same, there being provided a single swing-- ing member having means for engaging the lock, the locking bolt for engaging the same remaining in the same relative position to the swinging member regardless of the position of the stanchion.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure l is an elevation of the complete stanchion with the present invention applied thereto, Fig. 2 is an elevation and partial section of the casing with one section removed showing the portion carried by the stationary stanchion member and the portion carried by the swinging member in locked relation. Fig. 3 is an enlarged detail view of the locking bolt and actuating mechanism. Fig. at is a top plan view of the lever for actuating the bolt. Fig. 5 is a bottom plan view of the locking bolt. Fig. 6 is a view similar to Fig. 2 taken at right angles thereto.

Referring to the drawings, the numeral 1 designates the lower or swivel connection for the stanchion with the floor while 2 designates the stanchion carrying bar which is disposed above and parallel tothe floor. The stanchion consists of the relatively stationary member 3 and the pivoted member 4. Connected to and carried by the upper end of the stationary member 3, are two castings 5, which are so formed as to embrace the upper end of the member 3 and be secured thereto, each casting being provided with outwardly extending arms (5, which. when assembled constitute a guiding yoke for the locking end 16 of the swinging member 4. These castings 5 when assembled form a circular boss 7 having the central bore 8 with a reduced portion 27, the purpose of which will presently appear. The annular rim or flange 9 with its boss 7, rotatably fits in the aperture 10, formed by the reinforced portion of the sections 11 of the sasing supported fixedly from the bar 2.

The sections 11 of the lock carrying casing and that portion forming the female connection of the swivel joint are held together by means of the bolts 12, and in the upper portion of said sections, is formed the longitudinal sleeve 13 which provides a channel for the bar 2 and upon which the sections 11 are clamped. Secured in the upper end of the swinging member l is a boss 17 of the locking member 16, the same being so positioned as at all times when moved toward the locking sections 11 to pass between the forked ends 6 and into the socket formed in the end of the castings .5, there to engage the reduced end 15 of the locking bolt 14, all as clearly illustrated in Fig. 2.

In order to properly actuate the locking.

bolt 14 to release the swinging member 4., when desired, an integral stud 19 carried by the locking bolt 14L and provided with the reduced stem 20 and head 21, is fitted within the forked end 23 of the pivoted bolt actnating lover or arm 22, the same being mounted upon one of the bolts 12 and held downwardly and resiliently by means of the spring 25), whose terminal or bail 26 engages the forked end 23 of the arm or lever 22. The coils of the spring 25 are wound upon the bolt 12, as clearly shown in Figs. 2 and 3.

To insure the rotation of the locking bolt 14 with the swivel joint, so that the locking end 15 will always be in position to engage the locking end 16 of the swinging member at, the rib 18 is formed integral with the locking bolt 14 and is seated slidably within the recessed portion 27 of the two castings 5, the same forming in a reality a key and key way, respectively.

In order to release the locking bolt 14, to permit of the swinging member a being disengaged from the stationary member 3, the

bail 28 is journaled within the respective sections 11 of the lock casing, and is provided with the exteriorly disposed handle 20 which when moved to the right as viewed in Fig. 1, will elevate the lever 22 and consequently retract the bolt 14; so that its looking end 15 will be disengaged from the looking head 16 of the member 4. An off set handle 30 is carried by the handle 29 to form a ready means for manipulating the same 20 to release the animal.

The swivel connection 1, is identical with that shown in the present applicants U. S. Letters Patent No. 1,001,071, and in connection with the present device is readily adaptable.

From the foregoing description, taken in connection with the drawings, it is evident that with a stanchion constructed according to and embodying the present invention,

that the swinging member 4.- is quickly locked and from any direction, regardless of the position thereof, as the locking bolt 14 will always be in the proper position. Also that by reason of the handle 29, the locking bolt is readily released to permit the swinging member 4 to fall and release the animal. By constructing the locking head 16 as shown, the handle 29 does not have to be manipulated when the stanchion is placed about the neck of the animal.

lVhat is claimed is:

1. The combination with a two-membered stanchion, of a support and locking device for the upper ends thereof, including a sectional casing havingareduced opened lower end, a hollow boss carried by one member of the stanchion and rotatably mounted in the open end of the casing, a bolt vertically slidable within the boss, a bolt engaging portion carried by one end of the other member of the stanchion, a spring actuated lever disposed within the casing and operably connected to the bolt, and means mounted in the casing and operable exteriorly thereof for retracting the lever and 1 bolt against the spring.

2. The combination with a twounembered stanchion, of a support and locking device for the upper free ends thereof, including a vertically separated two-part casing, the

upper portion of which is a support engaging portion while the lower portion is a lock containing portion and is provided with a vertically disposed circular aperture, a flanged boss projecting through the aperture and mounted for rotation within the casing, said boss being provided with an irregular shaped opening theret-hrough, a bolt fitting in said irregular shaped opening and held against rotation thereby, said bolt being provided with a reduced and headed upper end disposed within the easing, a spring actuated lever mounted in the casing and engaging the reduced upper end of the bolt to project the lower end of the bolt into locking position, a stanchion member engaging portion carried by the boss, a locking member carried by the free end of the other stanchion member, and a lever actuated crank arm mounted in the casing for operating the lever to retract the bolt against the spring.
